My next-door neighbour had this exact model
of machine. It's BOL, or darn near. Never quiet, it was LOUD when it got old. Hers ran without trouble for 20 years.
It's from the early 70s.
She would go away for the summer, and when she was gone, she asked me to run it once a month. (Not being a fool, I would take over a load of sturdy cottons. It worked well, but did not have a slow speed.)
If I had the room, I'd be interested, because it's not too far from here, but I do not have room.
